Conway's life game suggests many things.
Something that keeps solidifying all the time
Things that keep moving
That which disappears
What is born
The rules are simple, but they are based on a perfect balance.
Phenomena that happen before your eyes can be seen forever.

Unique hashes move by the rules of the game of life.
Long-lived things become brighter and brighter.
Tunnels that move in all directions and explosions that spread out from the center force complex rules onto pixels.
Our activities are also pixels somewhere.
